Formed in place (FIP) gasket arrangement

Abstract

An FIP (Formed In Place) gasket arrangement includes three hollow parts which are joined with each other in such a way as to sealingly separate the inside and outside thereof. Two of the parts have surfaces which are flush with each other and adjoin at a line extending between the inside and outside of the two parts. The remaining one of the parts has a surface joined with the surfaces of the two parts by interposing therebetween an FIP gasket. The two parts also have edges extending along the above mentioned line, one of the edges being partially chamferred to provide a chamber. The FIP gasket has a portion filling the chamber.

What is claimed is: 
     
       1. A formed in place (FIP) gasket arrangement comprising: first, second and third parts which are hollow and joined with each other in such a way as to sealingly separate the inside and outside thereof;   said first and second parts having joining surfaces which are flush with each other and adjoin at a line extending between the inside and outside of said first and second parts;   said third part having a joining surface joined with said joining surfaces of said first and second parts;   an FIP gasket interposed between said joining surfaces of said first, second and third parts;   said first and second parts having edges extending along said line;   one of said edges being partially cut to provide a chamber surrounded by said first, second and third parts;   said FIP gasket having a portion filling said chamber.   
     
     
       2. An FIP gasket arrangement as set forth in claim 1 wherein said cut portion of said edge is a nearly half portion of same located closer to the inside of said first and second parts. 
     
     
       3. An FIP gasket arrangement as set forth in claim 1 wherein said cut portion of said edge is a nearly half portion of same located closer to the outside of said first and second parts. 
     
     
       4. An FIP gasket arrangement as set forth in claim 1 wherein said cut portion of said edge is a central portion of same. 
     
     
       5. An FIP gasket arrangement as set forth in claim 1 wherein said cut portion of said edge is an end portion of same, and said partially cut edge is further cut at the other end portion thereof to provide a chamber surrounded by said first, second and third parts, said FIP gasket having a portion filling said second mentioned chamber. 
     
     
       6. An FIP gasket arrangement as set forth in claim 1 wherein said cut portion of said edge is a portion which is largely cut, and said edge includes the remaining portion which is slightly cut. 
     
     
       7. An FIP gasket arrangement as set forth in claim 6 wherein said largely cut portion is a nearly half portion of said edge located closer to the inside of said first and second parts. 
     
     
       8. An FIP gasket arrangement as set forth in claim 1 wherein said cut portion of said edge is a chamferred portion. 
     
     
       9. A formed in place (FIP) gasket arrangement comprising: first, second and third parts which are hollow and joined with each other in such a way as to sealingly separate the inside and outside thereof;   said first part having first and second surfaces intersecting at an edge;   said second part having first and second surfaces intersecting at an edge;   said first and second parts being joined at said second surfaces in such a way as to make said first surfaces flush with each other and said edges meet at a line extending between the inside and outside of said first and second parts;   said third part having a surface joined with said first surfaces of said first and second parts;   an FIP gasket interposed between said first and second surfaces of said first and second parts and said surface of said third part;   one of said edges being partially cut to provide a chamber defined by said cut edge portion of one of said first and second parts, said second surface of the other of said first and second parts and said surface of said third part;   said FIP gasket having a portion filling said chamber.
